A type of portable jar (complete with a cap) able to hold much water, and only water.

"The military uses water canteens which are put into pouches. Or should I say they used to. Now there is a straw beside them which allows them to move their lips sideways to slurp. Kinda nice, not to mention hi-tech, but let's hope it doesn't foster laziness."

The lunch room for the guy at the depot. The canteen is now Dum Dums (who is from whoreleons) turf. If you buy anytings from any other source (Glen), Dum Dum will scream at you until he is on the brink of a stroke. The main food groups sold at the canteen are Chucks, Twix saputo products and of course, toass. Some guy steals from the depot to run his grow operation.

"Guy, we have a viande in the Cantsteens today, because some guy steal from the cantsteens and some other guy put the toass in the wrong slots!"
